动态干扰光对人的视觉、心理、情绪的影响

Effects of Dynamic Obtrusive Light on Vision,Psychology and Emotion

动态干扰光是城市光污染的主要表现形式之一。文章通过模拟动态光环境,实验研究了背景亮度、距离和刺激速度三因素的组合和交叉变化对人的视觉、心理、情绪的影响。应用统计学方法定量分析了背景属性和性别属性对被试主观反应因素影响的差异。实验结果表明,动态干扰光对人的心理感受和情绪反应干扰程度要比对人的视觉功能干扰强烈;影响被试总干扰评价水平的实验因素次序为视角、刺激速度与背景亮度,其偏Eta平方分别为0.280、0.271和0.078;女性对动态光的敏感性高于男性。

Dynamic obtrusive light is one of main light pollution.This paper simulated dynamic light environment in the laboratory and researched influences of three completely-crossed independent variables（namely background brightness,distance and stimulating speed） on human＇s vision,psychology and emotion.Quantitative analyses were carried on from background,gender and time attributes by statistical methods.Results indicated that dynamic light had an intense disturbance on human＇s psychology and emotion,whereas had little influence on vision.The main factors influencing subject＇s disturbance value level were the visual angle,stimulating speed and background brightness,the partial eta squared being 0.280、0.271 and 0.078 respectively.Women had higher sensitivity on dynamic light than men.
